Dear vtk users and developers,<br>
<br>
<br>
I have a series of point clouds that describe a 3d scene. I'm trying<br>
to register them all in the same coordinate system, preferably using<br>
iterative closet points algorithm. Can I do this using<br>
vtkIterativeClosestPointTransform ? I have my data stored as<br>
vtkPoints in vtkPolyData but vtkIterativeClosestPointTransform says it<br>
only maps surfaces. Are there any better examples using ICP?<br>
<br>
Thanks,<br>
<br>
John<br>

The implementation does not allow for partial overlap at all, all points must have a good match, or one set must be a strict subset of the other to get reasonable results.<br><br clear="all">Thanks,<br><br>David<br>
